He doesn't look good player but especially from bad players and if you face such moves you will very often see KK/AA which are trapping like that. Therefore I might even give it up preflop than continue there. We really have to know that he is capable of 4betting that easily with pure crap to make it profitable. And even if you want to continue, why don't you just ship it preflop? I don't really see why to Call it and then ship the flop, what's the difference?
